AHEAD OF THE FLOW
®
The patented technology of the 3-in-1 NIB-SEAL locking handle solves three problems at
once: it extends, it insulates, and it locks. The innovative locking handle design extends
valve actuation to provide ample room for insulating around piping systems, and its unique
thermal barrier system prevents heat transfer and condensate development. The NIB-SEAL
locking handle also allows the valve to be locked in the full open or closed position to pre-
vent incidental actuation.
Designed for new installations, the NIB-SEAL locking handle is engineered to work with NIBCO
®
bronze ball valves.**
Applications: For piping systems requiring up to 2” of insulation, specify a non-conductive
CPVC extended-locking handle bronze ball valve tested to UL 2043, and UL listed for installation
in air handling spaces. The assembly offers a vapor seal, position indicators, locking device, and
actuation without disturbing the insulation. Designed for new installations, the NIB-SEAL locking
handle installed on bronze ball valves offers a wide range of advantages for typical commercial
HVAC systems as well as industrial applications where insulated piping with a locking device is
desirable. Specify NIB-SEAL insulated locking handle.
Approvals: UL 2043
Safety Lock Compatibility: Cable lock as small as ⅛" diameter to padlock as big as 0.33”
diameter shackle.
Temperature Range: 15° F to 250° F
Not intended for steam applications in excess of 15 psi.
